This also allows us to move some code from preprocessing to compiling (gcc culls dead code) which should help with code quality (readability, catch minor bugs, etc...).

There is no invalidate only instruction it's always: FLUSHINV So when we "invalidate" after the DMA we might (do) overwrite freshly dma'ed data by dirty Cache WB content. Fixed by moving the "invalidate" at the beginning of dma_memcpy.
